CFRP Structural and Visual Parts

Mubea develops CFRP product solutions and the corresponding production technology. This results in car body structure and hybrid components in large production runs as well as complex monocoques and exclusive CFRP visual parts featuring a thermoset and thermoplastic matrix.

CFRP visual parts featuring a thermoset and thermoplastic matrix : TOP APPEARANCE MADE IN EUROPE

The best technologies, tailored to your needs and requirements:
Fiberject®—complex-shaped and high-accuracy CFRP visual parts with fully integrated functions and thermoplastic matrix for large quantities.


Mubea Fiberject®

Highly accurate, groundbreakingly cost-effective

Mubea Carbo Tech has developed an innovative procedure that combines the design freedom of conventional thermoset applications with the numerous advantages of thermoplastic series production to enable the manufacture of complex-shaped, functionally integrated CFRP components in large quantities. With the patented Fiberject process and the use of thermoplastics, we are able to produce the most challenging shapes for CFRP visual parts—without any folding or deformation. The single layer of CFRP is back-molded including any additional inserts —with significantly higher positioning accuracy than when bonded manually.


The end products exhibit excellent surface quality, because the thermoplastic outer layer compensates for any sink marks even after several temperature cycles. To meet all automotive requirements, Mubea Carbo Tech has developed a customer-specific thermoplastic compound and even allows an outdoor application without protective lacquer.



  • Excellent visual CFRP appearance, greater transparency and depth than established epoxy-based duroplastic CFRP components.
  • In contrast to manufacturing processes using organic coated sheet metal, our development enables the production of components with highly complex shapes, including undercuts, cut separations with very high draping and forming degrees.
  • Dramatically reduces manufacturing time through reduced draping and faster consolidation. The injection molding process as a central manufacturing step enables the highest levels of accuracy and process capability.
  • Can be used for automotive interior and exterior applications with the possibility of avoiding clear lacquer and eliminating VOCs as far as possible.
  • Recyclable due to the use of a thermoplastic matrix.


CFRP monocoques are the pinnacle of the evolution in lightweight automotive construction. RTM monocoques manufactured in a single operation enable significant weight reduction and a high level of functional integration for larger vehicle series.


One-piece CFRP structural cell with maximum lightweight construction for automotive series applications

The innovative production steps of our RTM CFRP monocoque are as follows:

  • Automated manufacture from preform to RTM component
  • Use of hollow structures (blow core technology) to reduce weight without loss of performance
  • High-performance connection of chassis components by means of metal inserts

As a result, we offer you major advantages:

  • Up to 30 percent weight reduction compared with aluminum structural cells
  • Improved safety for the vehicle occupants
  • Cost-effective manufacture thanks to minimal material use and RTM processes


We offer optimized structural and shell solutions for covers, flaps, and doors—in class A and CFRP visual optics. The focus is on maximum functional integration and on meeting the highest optical quality requirements.

MBE Spiegel Technisch

Maximum functional integration reduces weight and cost without loss of performance

Our door structures:

  • The use of hollow structures (blow core technology) and foam cores enables the previous multipart solution to be integrated into one component
  • Realization of all interfaces to the vehicle through metallic inserts
  • Automated manufacture for large series


As a result, we offer you decisive advantages:

  • Weight saving of 30 percent compared with the standard CFRP solution
  • Significant cost reduction due to improved material usage and no joining required
  • Rigidity, strength, and mechanical characteristics retained


Shell components: Covers and flaps

High functional integration and class A and CFRP visual surfaces without loss of optical quality

Information about our shell components:

  • Fulfill highest surface requirements
  • Functional integration of component interfaces
  • Automated manufacture for large series

As a result, we offer you major advantages:

  • 30 percent, up to 50 percent with maximum integral construction


By using an RTM process, we are able to offer CFRP roofs with visual optics cost-effectively and for series production. This means that the extensive use of CFRP visual components is not restricted to exclusive vehicles.


Weight reduction with improved driving dynamics for large series applications

Our CFRP roof in production:

  • Automated manufacture from preform to RTM component
  • Production lines designed for large series (>100,000 pieces per annum)


As a result, we offer you the following advantages:

  • Up to 30 percent weight reduction compared with an aluminum roof
  • High-quality CFRP visual optics
  • Cost-effective manufacture


By combining fiber-reinforced plastics (FRP) and metallic components, we are achieving a new dimension in lightweight construction with optimum functionality.

Hybrid B-Säule

Hybrid columns

The innovative lightweight construction solution made of steel and FRP for large series applications

Our hybrid B-pillar:

  • FRP shell with load-balanced optimization of layer construction and alignment for maximum lightweight construction
  • Function-optimized interaction between FRP component and steel component with adjustable wall thicknesses and material properties
  • The joining concept with mechanical elements and bonding guarantees the secure connection of the FRP and steel components over the entire life cycle

As a result, we offer you the following advantages:

  • Up to 40 percent weight reduction
  • Conventional joining processes enable integration in shell construction
  • Lightweight construction concept suitable for large quantities

Integral underbody: The cost-effective lightweight construction underbody

Our integral underbody:

  • Highly integrated structural components
  • Manufacture in conventional shell construction plants
  • Online coating together with car body and add-on parts


As a result, we offer you decisive advantages:

  • Up to 50 percent weight reduction compared with conventional steel modular elements
  • Substantial cost reduction in comparison with conventional monocoque method of construction
  • Suitable for large production runs
  • Integration of up to 60 components
  • Increased rigidity
  • Improved crash performance


Leichtbau Carbon Hybrid Sitz

From prototype through validation to series production

Featuring integrated functions, our seat shells made from CFRP, organic coated sheet metal or hybrid structures, reduce weight by around 30 percent compared with conventional solutions.

Assembly times are also significantly shortened. The wide range of options for individualization and the expertise of our developers mean that we are able to offer:

  • Cost-effective individualization
  • Customized design
